The DS4412U+ is a low cost, dual channel, 4bit I2C adjustable sink/source current digital to analogue converter (DAC) in 8 pin μSOP package. The two I2C adjustable current DACs are capable of sinking or sourcing current. Each output has 15 sink and 15 source settings that are programmed by I2C interface. The full scale range and step size of each output is determined by an external resistor that can adjust output current over 4:1 range. The output pins (OUT0 and OUT1) power-up in a high impedance state. The DS4412 is used in power supply adjustment and power supply margining applications.
